Abstract

we proposed a novelty and scheme for quantum teleportation of deterministic of arbitrary two qubit state via GHZ-like as quantum channel. Compared with previous scheme, the advantage of our scheme is that Alice's unitary operation simpler and the total probability of successful and fidelity reaches to 1.

Deterministic remote preparation of arbitrary two- and three-qubit states

You-Bang Zhan

\n Recently Liu et al. (EPL, 87 (2009) 30006) have proposed two new schemes for probabilistically preparing arbitrary two- and three-qubit states with complex coefficients based on two- and three-qubit projective measurement, respectively. In this letter, we present a possible improvement of the successful probability for their schemes. For this purpose, we put forward two novel schemes for remote preparation of arbitrary two- and three-qubit states with complex coefficients via two and three GHZ states as the quantum channel, respectively. To complete the schemes, two novel unitary operations have been introduced. Compared with the previous schemes, the advantage of our schemes is that the total successful probability can reach 100%.\n

Remote preparation of arbitrary two-qubit state

Guo-Fang Shi

Inspired by the idea of Wang and Yan's,i.e.,a two-step exact remote state preparation(RSP) of an arbitrary qubit,the remote preparation of arbitrary two-qubit state was studied.In the scheme,two non-maximally entangled GHZ states act as quantum channels.The sender Alice divides the full information encoded in known state into two parts,one purely real coefficient and the other purely real phase factor. After twice projective measurements and the transmission of 4-bit classical information by Alice,the remote receiver Bob can obtain the desired state with the success probability 4|βγ|~2 which is higher than that in Liu's protocol and it is also the advantage of our scheme,because only two-qubit state in real.Hilbert space or equatorial-like state can reach this success probability value in Liu's protocol.

Deterministic joint remote state preparation of arbitrary two-and three-qubit states

王媛, 计新

We propose a novel deterministic protocol that two senders are capable of remotely preparing arbitrary two-and three-qubit states for a remote receiver using EPR pairs and GHZ state as the quantum channel.Compared with the existing deterministic protocols [An et al.2011 Phys.Lett.A 375 3570 and Chen et al.2012 J.Phys.A:Math.Theor.45 055303],the quantum resources and classical information in our scheme are decreased,and the whole operation process is simplified.

Deterministic Controlled Remote State Preparation of Arbitrary Real-parameter Multi-qubit States via Three-qubit Entangled States

Kaihang Zhou, Lei Shi, Jiahua Wei +2 more

This paper offers a theoretical protocol for deterministic controlled remote state preparation of arbitrary real-parameter multi-qubit states, in which the maximally three-qubit entangled states are used as quantum channel. We elaborate the processes of implementing remote state preparation of the real-parameter two- and three-qubit states, and extend the protocol to realize the real-parameter n-qubit states. By performing the appropriate multi-qubit projective measurement basis and multi-qubit unitary operations, the successful probability of our scheme can reach 100%.

Probabilistic Remote State Preparation of an Arbitrary Two-Qubit State via Two Three-Qubit Partially Entangled States

毅琼 徐

本文提出了一种基于两个三粒子部分纠缠GHZ态的任意两粒子远程态制备方案。此制备协议并不需要引入辅助粒子,总体成功概率等于纠缠通道两个最小幅值模平方之积。结合具体幺正矩阵与测量基形式,本文给出了制备协议实现步骤。当纠缠通道取为两个最大纠缠GHZ态时,总体成功概率则等于1/4。 In this paper, we presented a novel scheme for probabilistic remote preparation of arbitrary two-qubit state via two three-qubit GHZ states. Any auxiliary particles need not to be introduced in our proposal. The total successful probability is equal to the square of the norm of the minimum amplitude coefficients of the partially entangled channel. The concrete processe of this scheme is presented via some appropriate local unitary operations and measurement basis. When quantum channel is composed of two three-qubit maximally entangled states, the successful probability is equal to 1/4.
